As the name implies rubber sheeting involves stretching and warping an image to georegister control points shown in the image to known control point locations on the ground. Rubber sheeting is commonly used after a transformation to further refine the alignment accuracy of the transformed features. The input link features represent the regular links. Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.

Conveyor belts lacing. In rubbersheeting adjustments you are usually trying to align one layer with another that is often in close proximity. The source layer drawn with solid lines is adjusted to the more accurate target layer. The input point features represent identity links that hold source positions unmoved during the rubbersheeting process.

Rubbersheeting is typically used to align two or more layers. Random geometric errors are corrected through a process known as rubber sheeting. Rubber sheeting registration by relative position is the procedure using slave and master mathematical transformations to adjust coverage features in a nonuniform manner. On the edit tab in the snapping group enable your snapping preferences.

Use displacement links to define common locations in the source and target layers. Before aerial photography arrived most maps were highly inaccurate by modern standards. The source layer drawn with solid lines is adjusted to the more accurate target layer. This exercise will show you how to rubber sheet data by using displacement links multiple displacement links and identity links.

Rubber sheeting may improve the value of such sources and make them easier to compare to modern maps. Features may move depending on their proximity to and length of displacement links.

For steps to transform features using affine or similarity transformation methods see transform features. This process moves the features of a layer using a piecewise transformation that preserves straight lines. Rubbersheeting makes spatial adjustments to align the input feature locations with more accurate target feature locations based on the specified rubbersheet links. Rubber sheeting is a useful technique in historical gis where it is used to digitize and add old maps as feature layers in a modern gis.
